P856 Ticket Machine - Gibson

P856 Ticket Machine - Gibson
Ticket Machine - Gibson A14

This famous bus ticket machine type was made for London Transport by Ticket Equipment Ltd, of Tring, Hertfordshire. These reliable machines were designed by George Gibson, London Transport’s Ticket Machine Superintendent.

The Gibson A14 is an improved version of the previous TIM machine. It works on the same general principle except that there are fourteen discrete fare values set by the conductor's left hand. The fare stage and ticket type is set by their right hand. The detent button, to prevent accidental issue, is above the fare window on the left side, with the issuing handle being on the right. Clever conductors would wear this machine low, hipster style, then issue single handed by pressing the detent button whilst twisting the now free fare wheel.

This machine type was introduced on London bus routes in 1953.

When decimal currency was introduced in February 1971 the machines were modified by grinding off the 'd' on the print wheel so that, for instance, 1/1d became 11 new pence. Later, new print wheels were fitted, but with constantly increasing fares the machines were converted to Alpha codes in which, for example, 'A' on your ticket signified 15 new pence. A notice posted in the bus indicated what Alpha code equated to what value fare you had purchased from the conductor.

Inside the workings, a drum with moveable type parts, set by the fare, ticket type, and fare stage dials, rotates over an inked roller then onto the paper roll. This is propelled by rubber rollers during the printing. At the same time, counting registers are operated to maintain totals for each of the fare categories. These registers are visible below each fare setting through the little window.

The Gibson was finally withdrawn in 1993.
